The ringfort that once enclosed this site has been almost completely destroyed, its circular earthwork reduced to the point where little trace remains above ground. Yet beneath it, a souterrain persists. A souterrain is an artificially constructed underground passage or chamber, typically built during the early medieval period and associated with ringfort settlements, used variously for storage, refuge, or as a means of concealed movement. That the underground structure survived where the surface monument did not is a quiet inversion of the usual order of things.

The ringfort, recorded as KE044-105, was roughly circular in plan, a common form across early medieval Ireland when enclosed farmsteads of this type were widespread across the landscape. The souterrain beneath it was noted as large by Ashe in 1954, a description recorded in J. Cuppage's archaeological survey of the Corca Dhuibhne region published in 1986. Beyond that single adjective, the details are sparse. The Dingle Peninsula is dense with such remains, its western reaches having preserved an unusual concentration of early medieval and prehistoric monuments, and Baile Na Saor Íochtarach sits within that broader pattern, though its above-ground monument has not fared as well as some of its neighbours.
